CVE-2026-1589 identifies a SQL Injection vulnerability in itsourcecode School Management System version 1.0, specifically within the /ramonsys/inquiry/index.php file. The vulnerability arises from improper sanitization of the txtsearch parameter, which is directly used in SQL queries without adequate validation or use of parameterized statements. This allows an unauthenticated remote attacker to inject arbitrary SQL code, potentially extracting, modifying, or deleting data from the backend database. The vulnerability does not require user interaction or prior authentication, increasing its exploitability. The CVSS 4.0 score of 6.9 reflects a medium severity, considering the network attack vector, low complexity, and no privileges or user interaction needed, but limited impact on confidentiality, integrity, and availability (each rated low). Although no known exploits are currently active in the wild, the public disclosure of the vulnerability increases the likelihood of exploitation attempts. The affected product is a school management system, which typically stores sensitive student and staff information, making the impact significant if exploited. The lack of available patches necessitates immediate mitigation through code review and secure coding practices. The vulnerability highlights the importance of input validation and use of prepared statements to prevent SQL Injection attacks.

For European organizations, particularly educational institutions using the itsourcecode School Management System 1.0, this vulnerability poses a risk of unauthorized access to sensitive student and staff data, including personal identifiable information and academic records. Exploitation could lead to data breaches, data manipulation, or denial of service by corrupting database contents. This could result in regulatory non-compliance with GDPR, reputational damage, and operational disruptions. The medium severity indicates that while the impact is not catastrophic, it is significant enough to warrant urgent attention. Since the attack can be performed remotely without authentication, attackers can exploit this vulnerability at scale if the system is internet-facing. The lack of known exploits in the wild currently provides a window for proactive mitigation before widespread attacks occur. However, the public disclosure increases the risk of opportunistic attackers targeting vulnerable systems. European educational bodies must assess their exposure and prioritize remediation to protect sensitive data and maintain service integrity.

1. Immediately review and sanitize all inputs to the txtsearch parameter in /ramonsys/inquiry/index.php, ensuring that user-supplied data is properly validated and escaped. 2. Refactor the code to use parameterized queries or prepared statements to prevent SQL Injection. 3. Restrict database user permissions to the minimum necessary to limit the impact of potential exploitation. 4. Conduct a comprehensive code audit of the entire application to identify and remediate other potential injection points. 5. Implement Web Application Firewall (WAF) rules to detect and block SQL Injection attempts targeting the vulnerable parameter. 6. Monitor logs for suspicious query patterns or repeated failed attempts to exploit the vulnerability. 7. If possible, isolate or restrict access to the affected system from the internet until patches or mitigations are applied. 8. Educate development and IT teams on secure coding practices to prevent similar vulnerabilities in future releases. 9. Engage with the vendor or community to obtain or develop official patches or updates addressing this vulnerability. 10. Ensure regular backups of critical data to enable recovery in case of data corruption or loss due to exploitation.
